Romo went through individual drills during the portion of practice open to the media.
Romo will not play Thursday against the Denver Broncos, and the Cowboys won't have a full practice again until Saturday as they up their preparation for the Sept. 7 opener against the San Francisco 49ers.
Running back Joseph Randle (oblique), wide receiver Dwayne Harris (hip, ankle), cornerback B.W. Webb (hip flexor) and safety Jakar Hamilton (hamstring) were doing rehab work on the side, as was defensive tackle Terrell McClain. Defensive end George Selvie (shoulder), cornerback Justin Green (hamstring), safety Johnny Thomas and tackle Darrion Weems (shoulder) were not spotted on the practice field.
The Cowboys have to make 13 roster moves by 3 p.m. Tuesday to reach the 75-man roster limit. Three players are likely headed to injured reserve: Ben Gardner (shoulder), DeVonte Holloman (neck) and Jordan Najvar (Achilles).
